Yeah, that is definitely correct that you would not approach building a NURBS surface with the intent of trying to sub-d its output later. You generally build it to the smooth shape directly with the NURBS.

But the kinds of things that you might want to do in ZBrush are totally different than sub-d smoothing, things like applying relief designs to "bubble" up from the base surface, distressing a model with pits and craters, adding finer sculptural type details...

Those are things that can be done well with a brush-based displacement type system which is just another totally separate system from a sub-d modeling system.
